I like the overnight shipping. It'd be pretty awful if you had to order one weeks in advance.
Anyway, as someone who's already bought a coffin, I'd definitely consider these. But I suspect it would have been hard to interest me if I was a first-time buyer.
Just to give you some background, I bought a cherry one for $5400 when my father died five years ago, so these prices look fairly attractive. I anticipate I'll probably need to buy another within the next decade. Both my parents taught me to plan ahead, y'know?
